Abstract
Abstract This invention is a mixing and dispensing apparatus having a filler housing means operably connected to a hardener housing means through a material control means so as to dispense and mix a filler material and a hardening material therefrom. More particularly, this invention is a mixing and dispensing apparatus operable under fluid pressure in order to separately dispense controlled quanities of filler and hardener materials into a rotating mixing chamber before dispensing and having means in order to be self-cleansing when moved to the de-activated condition to prevent hardening and resultant contamination of the mixing chamber.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
194 words
A mixing and dispensing apparatus adapted to hold, mix, and dispense first and second materials therefrom, comprising: a. a first housing means having a first material therein, b. a second housing means having a second material therein, c. a material control means having a mixing chamber operably connected to said first housing means and said second housing means to receive the first and second materials therein for mixing purposes, d. said material control means having an actuation control means connected to said first housing means and said second housing means to selectively force the first and second materials into said mixing chamber, and; e. said material control means including a control housing having a mixer and wiper means therein extended within said mixing chamber, said actuator control means operably connected to said mixer and wiper means; operable under one set of conditions to force the first and second materials into said mixing chamber for thorough agitation into a mixed material combination and operable under a second set of conditions to cease movement of the first and second materials and to seal said mixing chamber from air and to remove therefrom the mixed material combination.
Claim 2
Dependent Claim
194 words
A mixing and dispensing apparatus adapted to hold, mix, and dispense first and second materials therefrom, comprising: a. a first housing means having a first material therein, b. a second housing means having a second material therein, c. a material control means having a mixing chamber operably connected to said first housing means and said second housing means to receive the first and second materials therein for mixing purposes, d. said material control means having an actuation control means connected to said first housing means and said second housing means to selectively force the first and second materials into said mixing chamber, and; e. said material control means including a control housing having a mixer and wiper means therein extended within said mixing chamber, said actuator control means operably connected to said mixer and wiper means; operable under one set of conditions to force the first and second materials into said mixing chamber for thorough agitation into a mixed material combination and operable under a second set of conditions to cease movement of the first and second materials and to seal said mixing chamber from air and to remove therefrom the mixed material combination.
Claim 3
Dependent Claim
52 words

Claim 4
Dependent Claim
54 words
A mixing and dispensing apparatus as described in claim 2, wherein: a. said control means having a motor means connected to said actuator control means to receive said pressure source for operation thereof, and b. said motor means connected to said mixer and wiper means to rotate same under said one set of conditions.
Claim 5
Dependent Claim
59 words
A mixing And dispensing apparatus as described in claim 3, wherein: a. said mixer and wiper means having a mixer assembly connected to said motor means and a wiper assembly connected to said mixer assembly, and b. said mixer assembly having a mixer blade with outwardly extended protrusions to agitate the first and second materials in said mixing chamber.
Claim 6
Dependent Claim
78 words
A mixing and dispensing apparatus as described in claim 4, wherein: a. said wiper assembly having a wiper member mounted about said mixer blade having an inner contour conforming to the external contour of said mixer blade, and b. said wiper member having a peripheral shape conforming and engagable with a central bore of said mixing chamber to completely fill up the area between said mixer blade and said mixing chamber when under said second set of conditions.
Claim 7
Dependent Claim
51 words
A mixing and dispensing apparatus as described in claim 5, wherein: a. said wiper member is rotatable with and axially movable relative to said blade member, and b. under said one set of conditions, said actuator control means biases said wiper member through said mixing chamber to remove all materials therefrom.
Claim 8
Dependent Claim
107 words
A mixing and dispensing apparatus as described in claim 2, wherein: a. said control means having a cleanser assembly connected to said second housing means and said mixing chamber, b. said cleanser assembly having a closure housing and a closure member mounted with a flow channel in said closure housing from said second housing means to said mixing chamber, and c. said closure member operable under said first set of conditions to open said flow channel to move the first material to the mixing chamber and operable under said second set of conditions to close and seal said flow channel to prevent hardening of the second material.
Claim 9
Dependent Claim
41 words
A mixing and dispensing apparatus as described in claim 7, wherein: a. said closure housing having an adjustment cap thereon movable to adjust the opening into said mixing chamber from said flow channel to regulate amount of hardener material being dispensed.
